But last night, Reynolds went rogue. The "Deadpool" actor took to Twitter to target a new, unsuspecting victim — Hugh Jackman.

Jackman tweeted a photo in honor of his 22nd marriage anniversary with wife Debora-lee Furness, along with a sweet caption, "You and the kids are the greatest gift I will ever receive. I love you a gazillion times around the world."

Most people saw a sweet, innocuous message from a husband to his wife. Reynolds, however, saw — and took — an opportunity. He quoted the tweet and said, "I gave this three months. Tops. I was wrong."

Fans loved the jokey message.

Others saw it as an opportunity to post movie poster mockups for a potential Deadpool and Wolverine parody film.

So, while Reynolds' jab may seem like a unique occurrence to many onlookers, in reality, it is nothing new. And, most likely, it will continue occurring — to Lively, Jackman, and others — for many years to come.
